To V1f/ZZ whom t may conoerm.

Be it known that I, STACY'B. HART, a citizen of the United States of America, residing at Peoria, county of Peoria, and State of Illik nois, have invented certain new and ,useful 'more particularly pointed out in the claims.

In the drawings,.wherein like referenceletters indicate like vor corresponding parts, Figure 1 is a front elevation of 4a separator provided with my improved elevator with v parts broken away to show the construction.

Fig. 2 is a similar view showing the elevator equipped with a weighing and baggingdevice. ing the elevator hookedup against the side of the separator for transportation. Fig. fl is a partial side elevation of a separator equipped with my improvementl withgear-guard removed. Fig. 5 is atransverse section in line 5 5 of Fig. 7. Fig. 6 is'a front view of the top part of the elevator-tube in the preferred form, showing the tube inclined and the discharge-spout in a vertical position asin use; and Fig. 7 is a similar view showing the tube in a vertical position' and the discharge-spout inclined. 4

In the drawings, l is the side of the structure to which the elevator is attached-as, for example, a grain-separator.

2 is a bracket secured to the side Vof the structure adapted to support the elevator.

3 is the elevator-tube, supported by a double sleeve or band; 4 or equivalent means firmly securedl to a shaft or rod 5, adapted to be pivotally supportedI by the bracket 2. The tube is provided with a discharge-spout 6, preferably constructed to support a weighing or other equivalent device. In order to secure proper results, the wei ghin g device must be supported in a horizontal or level plane, as otherwise the results will be inaccurate. This Fig. 3 is a similar view to Fig. l, show-4 maybe securedin any preferred manner. As shown in Figs. 1, 2, and 3, the desired object issecured by finishing the end of the discharge-spout 6 on a horizontal plane when the tube 3 is placed at its normal inclination.

vI prefer in such construction to enlargel the end of the discharge-spout, as shown, extend ing the same in a direction away from the supporting structure, as shown at Fig. 7. This aids in securing asubstantial and firm support for thezweighingor. measuring de- -vice 8 and maintaining the .same in-a level position. unimpeded discharge.' Y

9 is a bagger, which may be of any preferred construction.

The device maybe equipped with any of It also aids in securing a free and the well-known forms of weighing or Ineasur-` ing devices, the mechanism `of which need not be here described. y

I0 is a jointed bar extending from near the upper end of the elevator tothe supporting structure.v The'length of the arm when extended, as shownin Figs. land 2,.is sufficient to give the lelevator the proper inclina-` tion to permit the boot ll to be positioned beneath the conveyer-spout l2 of the separator. Whenit is desired to transport the separator, the arm lO is benton its pivot 13, the bar 14, pivotally secured to'one member ofthe arm, engaging a pin I5 on the other to maintain the parts in position. The bar 14 may be provided with a plurality of transverse slots 16, adapted to engage the pin 15, so as to provide a limited field of adjusting the position ofthe elevator, Fig. 3. It will be apparent that in `moving the separator fromplace toplace the elevator is compactly maintained in position close tothe side of the separator, so as not to come in contact with obstacles met on the road-such, for example, as narrow gates and passages on the road, doorways&c. .On the other hand, when in operation the elevator is maintained in a position such distancefrom the side of the separator as will not interfere with the unimpeded operation of the belts and mechanism located on the side' of thel'se'parator.

A shaft 17 is provided with a .pulley 18,

. which is rotated by a belt 19,preferably driven by a pulley on the usual fan-shaft (not shown) or other'suitabl'e driven shaft. The shaft 17 IOO should be horizontal, as shown in Figs. 1 and 2, when the device is in operative position. The driving-shaft 20 for the elevator ought also to be parallel to the complemental shaft 21, near the top of the elevator. To provide for this construction, the shafts 17 and 2O are provided with geared pinions 22 and 23, respectively, an intermediate gear-wheel 24, mounted on a stub-shaft 25, meshing with both to rotate the shaft 2O in the proper direction, the several gear-Wheels being properly beveled to secure the change in the planes of their shafts, as described.

In the preferred form the discharge-spout G is extended at an angle from the elevatortube, as shown in Figs. 5, 6, and 7-that is, when the tube 3 is inclined the dischargespout more nearly approaches a vertical line, as clearly shown in Fig. 6. By this means the weighing or measuring mechanism is main tained upon a substantially vertical support, tending to insure more accurate and satisfactory results. I do not wish, however, to be understood as limiting myself to such form, as the form shown in Figs. 1, 2, and 3, in which the end of the discharge-spout is cut 0E on a horizontal plane When the elevator is inclined, will operate successfully. A suitable guard 26 protects the gears .22"23 24. A chain provided with suitable buckets or equivalent means aords means for elevating the grain.

It is obvious that after having thus described my improvement immaterial modifications may be made without departing from the spirit of my invention. Hence I do not wish to limit myself to the exact construction shown.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a grain-elevator, an elevator-tube constructed to be supported upon the side of a separator or the like with its top inclined ontward therefrom, in combination with a discharge-spout secured to the tube, arranged to discharge the grain in a direction parallel to the supporting-machine, and having its discharge end formed at an angle to the tube, so that when the tube is inclined the discharge end of the spout will be in a horizontal plane.
